Type A individuals may feel a need to do everything themselves and are likely to work more intensely and efficiently on tasks, while Type B individuals tend to be more relaxed and seek help from others. Type A personalities tend to be more impatient and frustrated with delays, while Type B individuals are more patient and tolerant of ambiguity and change.
